evan ad396d3f01 feat: Lua app firmware for the E32R40T display module
Boots to a launcher that lists /apps/<name>/main.lua on the SD card and runs
the selected app in a vendored Lua 5.4 with gui, input, fs, sys and log
bindings. Settings persist as a Lua table in /settings.lua, covering touch
calibration and screen rotation, with a settings app to edit both. Rotation is
applied after mapping raw touch into the panel's rotation-0 frame, so turning
the UI never invalidates a calibration.
